Uni has created a new writing system that is both extremely customizable and affordable. Like the higher end Sharbo X from Zebra, the Style Fit writing system gives you the freedom of choice to create a writing instrument that is as unique as you are. You can customize many aspects of your pen including what type of refills you want (gel, ballpoint, or mechanical pencil), the pen body and ink colors that you want, as well as the number of writing instruments you want to have (different sized bodies are available that can hold 1, 3, or 5 writing instruments).

Each writing instrument line consists of the best that Uni-ball has to offer. The ballpoint line contains the famous oil based, water and light resistant Jetstream ink that writes incredibly smooth. The gel ink line contains the popular Signo ink that is the same as that in the popular selling Uni-ball Signo line. The mechanical pencil is pre-filled with Uni-ball NanoDia Low-Wear pencil leads, which are infused with nano-diamond pieces to create an unusually strong and high-quality lead. The combination of all the above allows you to create a multi-pen that has all the best Uni-ball qualities in one single instrument. In addition, the system is eco-friendly since you can refill it again and again.

The light weight pen body is made of plastic and features a clear bottom portion that allows you to see ink color.

Polkadots! I will admit, I'm a bit biased because I ADORE polka dots... But I
think I would still like this pen if it didn't have polka dots. First and
foremost, the refills will only live a short time - they are tiny! The slide
mechanism for selecting the refill that you like isn't the most durable; it
feels like it would break after just a few clicks. (Though, mine has held up -
so maybe it just FEELS that way.)

Overall.. for the cuteness factor, I would rate this pen a 5/5. Unfortunately,
the plastic body makes it feel as if it will not last long enough to truly enjoy
the cute polka dots. I won't be purchasing a second body, but I will happily let
this pen live on my desk (rather than die in my "pen drawer").
